History of aluminum

  • An impure form of aluminum was prepared by Oersted two years earlier.
  • The existence of aluminum was predicted in 1808 by the English scientist Sir Humphry Davy.
  • The German chemist Friedrich Wöhler simplified the process in 1827 by using potassium instead of potassium amalgam
  • Aluminum was discoverd in 1825 in Copenhagen Denmark by Hans Oersted


Hans Christian Oersted

  • Hans Christian Oersted, a Danish chemist discoverd aluminum in 1825 in Copenhagen Denmark
  • Hans Oersted never went to school but because he taught himself some math and because he picked up some chemistry from when he went to work at he passed the entrance exam at the University of Copenhagen with honors.
  • He got a pharmaceutical degree in 1797 with high honors.
  • Hans Christian was also discovered electromagnetics

Facts

  • aluminum is the most abundant metal in the earth's crust, but it is never found free in nature. .
  • main mining areas are Surinam, Jamaica, Ghana, Indonesia, and Russia
  • Aluminum is the most common metallic element on Earth so it is common but many people still recycle aluminum
  • Aluminum has three isotopes Al-26, Al-27, and Al-28 and none of its isotopes are radioactive
  • The name aluminum is from the ancient name for alum, which was alumen
  • the name aluminium was adopted to conform with the -ium ending of most elements

Uses

  • consumer durables like appliances, cooking utensiles, ect
